Abstract (en)

[origin: US2009323821A1] Provided is a moving picture decoding apparatus including: a picture memory (103) that stores previously decoded picture data of a picture including macroblocks and macroblock information described on a macroblock basis, in association therebetween; an error judging unit (104) that judges presence or absence of an error for a current picture to be decoded; a picture data replacing unit (109) that replaces, when an error is present, picture data of the current picture to be decoded with that of a previously decoded picture in the picture memory (103); and a macroblock information replacing unit (113) that replaces macroblock information in association with the current picture to be decoded including an error with macroblock information stored in association with the previously decoded picture, or a macroblock information storage unit (602) that stores information that indicates presence of the error for the current picture to be decoded in association therewith.
